IMPROVEMENT IN WHEEL-CULTIVATORS.

Specification forming part of Letters Patent No. 206,961, dated August13, 1879;

application filed March 4, 1878.

To all whom it may concern:

Be it known that I, JAMES E. MUSTARD, of Glen Hall, in the county ofTippecanoe and State of Indiana, have invented a new and usefulImprovement in \Vheel-Oultivators, of which the following is aspecification:

Figure 1 is a top view of my improved cultivator. Fig. 2 is a verticallongitudinal sec tion of the same, taken through the line a .70, Fig. 1.Fig. 3 is a cross-section of the same.

Similar letters of reference indicate corre sponding parts.

The object of this invention is to furnish an improved wheel-cultivatorwhich shall be so constructed that it may have a direct draft, whichwill have no side draft, and will require less power to draw it thanordinary cultivators.

A are the wheels, which revolve upon the journals of the axle B. Theaxle B is bent four times at right angles, or nearly at right angles, toraise its middle part out of the way of the plants, and of the mechanismplaced beneath it.

The middle part of the axle B may be made of wood, and to its lower sideis bolted a circular plate or frame, 0, which forms the upper orstationary part of a fifth-wheel. To the center of the circular plate 0is pivoted the center of a corresponding; circular plate or frame, D,which forms the lower or movable part of a fifth-wheel, and to which isbolted the middle part of the bar E. The bar E is bent four times atright angles, and around its end parts are passed clevises E, which arebolted to the plow-beams G by a single bolt, so that the rear ends ofthe plow-beams may have a free lateral movement upon the said bolts orpivots. The movements of the clevises F upon the arms of the bar E allowthe rear ends of the plow-beams to have a free vertical movement. Theclevises F are kept in place upon the arms of the bar E by the U-bars orclevises H, which receive the elevises F between their arms, and haveholes formed in their ends to receive the arms of the bar E. Theclevises H are secured in place upon the arms of the bar E by set-screwsh, which pass through them and rest against the said arms, so that byloosening the said set-screw h the plow-beams G may be adjusted widerapart or closer together, as may be desired. To the ends of the bar Eare attached the ends of two chains, I, to the other ends of which areattached the whiffletrees J. The whiffletrees J are supported and keptfrom dropping down and breaking or injuring the plants by the chains K,the lower ends of which are attached to the center of the upper sides ofthe said whiffletrees J, and their upper ends are attached to the endsof a crossbar, L. The cross-bar L is pivoted at its center to the tongueM, which is bolted to the center of the axle B.

The ton gue M projects in the rear of the axle B, and to its rear end isattached a cross-bar, N, to the ends of which are attached twodownwardly-projecting hooks, 0.

If desired, the hooks 0 may be formed upon the opposite ends of a rodwhich passes along the upper side of the cross-bar N, and down throughits ends.

To the upper side of the plow-beams G are attached long staples P, to behooked upon the hooks O, to support the plows away from the ground whenpassing from place to place- To the opposite sides of the rear parts ofthe beams G are attached the upper ends of the standards Q, which arekept at the proper distance apart by blocks interposed between them andthe said beams G. The draft-strain upon the standards Q is sustained bythe braces B, the lower ends of which are attached to the saidstandards, and their upper ends are attached to the beams G.

S are the plows, which have semi-tubular sockets T attached to theirrear sides, to receive the rounded lower ends of the standards Q. Thesockets T are slotted transversely to receive the bolts U, that securethe plows S to the standards Q, so that the plows may be adjusted tothrow the soil toward or from the plants by loosening the nuts of thesaid bolts U. To the rear ends of the beams G are bolted the handles V,by means of which the plows are guided.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination of the arched draw-bar E and fifth-wheel O D with thearched axle B, the plow-beams G, and the independent draftconnection I JK L, substantially as shown and described.
